| Abstract: | The zooming movement of zoom optical lens is qualitatively analyzed according to operating principle of telescope. The movement equation for the lens moving lens set is derived according to the object-image relationship of the ideal optical system. The experimental setup controlled by the continuous zoom consists of a step motor, motor actuator and a control platform, and the control program is compiled with Visual C . The experiments show that the method can be convenient to realize zooming control of the continuous zoom optical lens. |
